Wisdom teeth (third molars) are the last teeth to develop and appear in the mouth. The normal position of wisdom teeth is behind the upper and lower second molars. The jaws of modern humans are not normally large enough to accommodate the four wisdom teeth. This is why wisdom teeth are usually removed. When the wisdom tooth is blocked from erupting or coming into the mouth normally, it is termed "impacted". Serious problems may develop from impacted or partially impacted teeth such as pain, infection, formation of cysts, crowding of

anterior teeth, and damage to adjacent teeth. If a cyst is formed and is not treated, a tumor may develop from the walls of the cyst and a more involved surgical procedure may be required for removal.

Many problems with wisdom teeth can occur with few or no symptoms. This can cause damage without your knowledge. As wisdom teeth develop, their roots become longer and the jawbone becomes more dense with age. Thus, it becomes more difficult to remove wisdom teeth and the complications become more severe. For these reasons, the surgeon may recommend the removal of wisdom teeth even if they are not yet causing problems, particularly for young adults.

Treatment of impacted wisdom teeth involves their removal using special surgical techniques. The removal of wisdom teeth can be performed on an outpatient basis, either in the dental office, or in certain cases, in the hospital setting. Normal activities can usually be resumed within a few days depending on the degree of impaction and the number of teeth removed.
